[C320-list] Engine mounts

[Warren Updike]

In 2006, DYI had an article on fasteners. As regards lock washers they
basically said they don't like them for the purpose of securing nuts:
"...lock washers not only do not work, they are dangerous and should not be
used."  What they recommend instead is a, "...alloy steel, through hardened
flat washer..."

They also caution that nylon lock washers are essentially a one-time use
item. 

Should anyone want a copy of this issue of DYI, e-mail me off-list and I'll
send it.

I found a broken engine mounts lock washer on our 1994 M30 Perkins. In the
photo below you can see the nut vibrated up about 1/2". Luckily the other
three mounts were still locked tight. The washer seem a little thin for the
size of the engine. Has anyone else run into this problem. I have a large SS
lock washer as a temp for now.  Thanks, John Mesa
